As the night grew darker, Bai Qi sent Cui Yongxuan out of the front yard.

Unintentionally catching a glimpse of Liu Yang, Bai Qi asked the guard next to him: "Has Deputy Commander Liu been here just now?"

"No, I just saw Deputy Commander Liu. I heard that Deputy Commander Liu was out on patrol," the guard replied.

Bai Qi thought for a moment and then walked towards Liu Yang.

"You are not on duty today, why don't you rest in the room for a while?"

Liu Yang knew Bai Qi's purpose of coming and did not choose to hide his whereabouts: "There have been a lot of things happening in the mansion recently. I wanted to have nothing to do, so I helped patrol to avoid the previous situation happening again."

The assassin who broke into the mansion in the past has not been found yet, and the defense of the mansion is constantly being strengthened.

Bai Qi didn't think much and said: "It's late at night, you should go back first, as long as I'm here."

"Yes." Liu Yang returned to his room obediently.

Bai Qi asked some more guards before returning to Cui Quan: "My lord, my subordinates have already inquired about the guards in the mansion. Liu Yang has been patrolling the mansion since the morning and has not come into contact with anyone except the people in the mansion.

"

Finally, Bai Qi concluded: "For now, Liu Yang is not suspicious. The person who sent the letter to Third Master should not be him, nor the person he sent."

Cui Quan frowned: "Are you from the mansion?"

Bai Qi thought for a while: "My subordinates have investigated and found that there is nothing unusual about the people in the mansion today, but today is the day when the farm stewards report monthly, and there are many farm stewards coming in and out of the mansion.

"Perhaps the messenger is hiding among these farm stewards."

After hearing this, Cui Quan ordered: "Check it out for me, and you must find the person who sent the letter to the third child."

"yes."

...

Four rooms.

Cui Yonglin lay on the bed, tossing and turning, unable to fall asleep. Later, he simply got up, put on his clothes and went to the main room.

"Fourth Master..."

When Yuyi came out with the teapot, she happened to see Cui Yonglin and saluted quickly.

"Shh-"

Cui Yonglin motioned her to be quiet, then looked into the room, took her aside, and reprimanded her in a low voice: "Didn't I tell you that at least two people should be left in the room to take care of the wife, why are you alone?

"Where did Madam Lu go?"

Yuyi did not dare to face Cui Yonglin and answered with her head lowered: "Madam can't sleep, so I asked Madam Lu to make the soothing soup."

"Then why did you come out?" Cui Yonglin asked.

Yuyi raised the teapot in her hand: "Ms. Lu is thirsty. I'm going to change the tea."

Hearing this, Cui Yonglin's face darkened: "I said that there must be no less people in Madam's room. Madam Lu is not here, and you are not here either. If something happens, can you be responsible?"

"Fourth Master, please calm down. I know I was wrong." Yuyi knelt on the ground to plead guilty.

"If you don't do this next time, you will be severely punished." Cui Yonglin said in a cold tone and took the teapot from Yuyi's hand.

Yuyi didn't dare to move.

Cui Yonglin walked a few steps and turned around to see Yuyi still kneeling on the spot. He was so angry that he walked back and scolded: "Why don't you go back to your room quickly and guard your wife?"

"Yes." Yuyi quickly got up, her feet were a little numb, but she didn't dare to delay and forced herself back to the main room.

Mrs. Cui Si was in the inner room, so when Cui Yonglin changed the pot of hot tea and walked into the room, Mrs. Cui Si did not see Cui Yonglin.

"Take good care of your wife, remember, you can't leave her alone." Cui Yonglin warned her carefully before walking out of the room.

On the way back to the study, he met Mrs. Lu who was coming back from making soothing soup. Cui Yonglin taught Mrs. Lu a lesson again.

In front of Cui Yonglin, Madam Lu very respectfully admitted her mistake and apologized. As soon as Cui Yonglin left, Madam Lu muttered aggrievedly: "There are only a few people in the fourth house, and now Yuyi and I are required to stay by Madam's side at the same time. How can we be errands?"

Well......"

But complaints are complaints, and the fourth master's order is also because he is worried about his wife, so they still have to find a way to fulfill it.

Not long after Cui Yonglin returned to the study, the man in gray quietly entered the study and closed the door.

"Fourth Master, my subordinate is back."

Finally waiting for someone, Cui Yonglin was a little excited. He walked out from behind the desk and asked impatiently: "How? Have you found it?"

The man in gray clothes respectfully replied: "Speaking of which, the third bedroom is the same as before, and there is nothing suspicious about it.

"If I have to say something suspicious, it would be that Yuanniang once sent a maid to bring snacks to the third master, who was in the study at that time.

"My subordinates have secretly investigated and found that the maid entered the courtyard but not the study. The snacks were brought in by the servant at the door."

Seriously speaking, there is nothing suspicious about this, but the person who entered the yard was sent by Cui Hengyue, so it is a little bit suspicious, because Cui Hengyue was investigating the cause of her brother's death.

Cui Yonglin also thought of this: "Where has Cui Hengyue been today? What did he do?"

"Same as the past few days, except for going to school, I have been staying in Jinglan Garden and haven't left the yard." The man in gray replied.

Cui Yonglin fell into deep thought and walked around the room unconsciously.

After a long time, Cui Yonglin's expression was still solemn, and he said slowly: "The person who sent the letter to the third child must be Yuanniang's people..."

The man in gray didn't ask why, he waited silently.

Sure enough, Cui Yonglin told the reason: "The mansion has been silent for fifteen years. If it were other people, they would have taken action long ago. Why wait until now?

"Only Yuanniang, not long after she returned to the house, so many things happened in the house, and she became suspicious of her brother's death and has been investigating the matter.

"So, what happened today should be her fault."

The man in gray finally spoke: "What are you going to do, Fourth Master? Do you want to inform the Duke of this matter?"

"No..." Cui Yonglin shook his head slightly: "Although my father has forgiven me, he doesn't trust me very much. I don't have evidence to prove that Yuanniang did this. Even if I tell him, he

I won’t believe it either.”

"Then what should we do? We can't sit still and wait for death, right?"

"Let me think."

Cui Yonglin returned to sit behind the desk, thought for a while, and finally made up his mind: "If Yuanniang did this, then the person who kidnapped Yuyi last night must be her, or one of her people.

"Well, you go and test it out..."

After listening to the instructions, the man in gray clothes immediately left the study.

An hour later, the man in gray clothes appeared in Jinglan Garden. He quietly opened the window, climbed in, and walked towards the person on the bed.

Cold light flashed, and the man in gray raised his dagger and stabbed the person on the bed.

Unexpectedly, the person on the bed suddenly opened his eyes, and at the same time grabbed the hand of the man in gray that was holding the dagger, twisted it hard, and took the dagger away.

At this time, the door opened, and a group of people came in with lanterns, and the room instantly became brighter.

The man in gray clothes was caught off guard. When he saw that the person who led the intrusion was Cui Hengyue, his face changed drastically. He turned back to look at the person who took away his dagger, and then he realized that the person lying on the bed just now was Cui Hengyue's maid, Shui Rong.

It turns out that he is from the Prince of Chu's palace, no wonder he is not weak in kung fu.
